Modification of problem types
Problem-related types in DifferentialEquations.jl are immutable. This helps, e.g., parallel solvers to efficiently handle problem types.
However, you may want to modify the problem after it is created. For example, to simulate it for longer timespan. It can be done by the
prob1 = ODEProblem((u,p,t) -> u/2, 1.0, (0.0,1.0)) prob2 = remake(prob1; tspan=(0.0,2.0))
A general syntax of
modified_problem = remake(original_problem; field_1 = value_1, field_2 = value_2, ... )
value_N are renamed to appropriate field names and new desired values.
